    Abstract: A method for detecting a movable object in a location includes —providing a first 3D representation of at least part of a surface by scanning; —providing a second 3D representation of at least part of the surface by scanning; —determining for the first 3D representation a first excluded volume; —determining for the second 3D representation a second excluded volume; —if a portion of the surface in the first 3D representation is located in space in the second excluded volume, the portion of the surface in the first 3D representation is disregarded, and/or —if a portion of the surface in the second 3D representation is located in space in the first excluded volume, the portion of the surface in the second 3D representation is disregarded.

    Abstract: Disclosed is a method and a scanner system for scanning interior surfaces, where the method comprises: - providing a probe shaped scanner having an axis, where the probe shaped scanner comprises: • at least one light source configured to create and project structured light, and • at least one camera configured to record 2D images; - entering said probe shaped scanner into a cavity of an object, where said cavity is bounded by an interior surface of the object; - creating and projecting structured light from said light source of the probe producing a pattern on the interior surface of the object; - recording a series of 2D images of the reflection of the pattern from the interior surface using said camera; - combining said series of 2D images to obtain 3D real world coordinates of the interior surface; and - providing data and processing said data such that surface information for areas of the surface, where image scanning is not complete, is created. The scanner system may comprise a probe shaped scanner, a data conversion device and a data processing device, optionally all integrated in one device. (fig.15 should be published)

    Abstract: Disclosed is a method for detecting a movable object in a location, when scanning a rigid object in the location by means of a 3D scanner for generating a virtual 3D model of the rigid object, wherein the method comprises:
    - providing a first surface by scanning the rigid object;
    - determining a first scan volume related to the first surface;
    - providing a second surface by scanning the rigid object;
    - determining a second scan volume related to the second surface;
    where the first scan volume and the second scan volume are overlapping in an overlapping/common scan volume;
    - if at least a portion of the first surface and a portion of the second surface are not coincident in the overlapping/common scan volume, then disregard the portion of either the first surface or the second surface in the overlapping/common scan volume which is closest to the focusing optics of the 3D scanner, as this portion of the first surface or second surface represents a movable object which is not part of the rigid object.
